lemon

The lemon is a small evergreen tree (Citrus limon) originally native to Asia, and is also the name of the tree’s oval yellow fruit. The fruit is used for culinary and nonculinary purposes throughout the world – primarily for its juice, though the pulp and rind (zest) are also used, mainly in cooking and baking. Lemon juice is about 5% (approximately 0.3 mole per liter) citric acid, which gives lemons a tart taste, and a pH of 2 to 3. This makes lemon juice an inexpensive, readily available acid for use in educational science experiments. Because of the tart flavor, many lemon-flavored drinks and candies are available, including lemonade.

Sambucus

Sambucus (elder or elderberry) is a genus of between 5 and 30 species of shrubs or small trees in the moschatel family, Adoxaceae. It was formerly placed in the honeysuckle family, Caprifoliaceae, but was reclassified due to genetic evidence. Two of its species are herbaceous.

The genus is native in temperate-to-subtropical regions of both the Northern Hemisphere and the Southern Hemisphere. It is more widespread in the Northern Hemisphere; its Southern Hemisphere occurrence is restricted to parts of Australasia and South America.

The leaves are pinnate with 5–9 leaflets (rarely 3 or 11). Each leaf is 5–30 cm (2.0–12 in) long, and the leaflets have serrated margins. They bear large clusters of small white or cream-coloured flowers in late spring; these are followed by clusters of small black, blue-black, or red berries (rarely yellow or white).

Apricot

The Apricot (Prunus armeniaca, “Armenian plum” in Latin, syn. Armeniaca vulgaris Lam., Armenian: Ծիրան “Tsiran”) is a species of Prunus, classified with the plum in the subgenus Prunus. The native range is somewhat uncertain due to its extensive prehistoric cultivation, but most likely is India.

It is a small tree, 8–12 m tall, with a trunk up to 40 cm diameter and a dense, spreading canopy. The leaves are ovate, 5–9 cm long and 4–8 cm wide, with a rounded base, a pointed tip and a finely serrated margin. The flowers are 2–4.5 cm diameter, with five white to pinkish petals; they are produced singly or in pairs in early spring before the leaves. The fruit is a drupe similar to a small peach, 1.5–2.5 cm diameter (larger in some modern cultivars), from yellow to orange, often tinged red on the side most exposed to the sun; its surface is usually pubescent. The single seed is enclosed in a hard stony shell, often called a “stone”, with a grainy, smooth texture except for three ridges running down one side

Rhubarb

Rhubarb is a group of plants that belong to the genus Rheum in the family Polygonaceae. They are herbaceous perennial plants growing from short, thick rhizomes. They have large leaves that are somewhat triangular shaped with long fleshy petioles. They have small flowers grouped in large compound leafy greenish-white to rose-red inflorescence. While the leaves are toxic, the plants have medicinal uses, but most commonly the plant’s stalks are cooked and used in pies and other foods for their tart flavour. A number of varieties have been domesticated for human consumption, most of which are recognised as Rheum x hybridum by the Royal Horticultural Society.

Cherry

Prunus cerasus, or the sour cherry, is a species of Prunus in the subgenus Cerasus (cherries), native to much of Europe and southwest Asia. It is closely related to the wild cherry (P. avium), but has a fruit that is more acidic and so is useful primarily for cooking.

The tree is smaller than the wild cherry (growing to a height of 4–10 m), has twiggy branches, and its crimson-to-near-black cherries are borne upon shorter stalks.

There are two varieties of the sour cherry: the dark-red morello cherry and the lighter-red amarelle cherry^.
